120 - 15% × 120 = x

Step-by-step explanation:

All given answers are incorrect.

15% means 0.15

She is not subtracting 15% or 0.15 from 120.

She is subtracting 15% of 120 from 120.

The correct answer is

120 - 15% × 120 = x

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
